Doctrine Enters Spain with Maite.ai Acquisition
Doctrine, a European leader in legal AI, has announced the acquisition of Maite.ai, a leading Spanish legal AI platform. This acquisition, Doctrine’s fifth in three years, marks the company’s entry into the Spanish market and brings its total customer base to 27,000 legal professionals across France, Germany, Italy, Spain, and Luxembourg.
Building a European Leader Tailored to Local Legal Specificities
Founded in 2024, Maite.ai has rapidly established itself as a leading provider in Spain’s legal AI market. In 2025, the company increased ARR 20-fold and now serves more than 2,000 customers, including solo practitioners, large law firms, corporate legal departments, and public administrations.
Maite.ai offers an advanced legal AI copilot that supports the full legal workflow by leveraging legislation, case law, and private user-uploaded documentation. Maite.ai’s technology has demonstrated exceptional accuracy, achieving a 99 per cent success rate on the Spanish judicial access examination.
This acquisition firmly establishes Doctrine’s presence in Spain and reinforces the company’s vision to build a European leader grounded in each country’s legal framework. The rapid adoption of Doctrine’s solutions is driven by the company’s unique market position, which combines deep expertise in local legal data (laws, regulations, commentary, and case law) with the private data of legal professionals (contracts, pleadings) to support every stage of their work. Doctrine provides legal professionals with a legal AI built on European technological sovereignty, fully GDPR-compliant and certified to ISO 27001 standards.
Profitable Organic Growth Accelerated by a Proven M&A Strategy
This transaction, Doctrine’s fifth in less than three years, further strengthens the company’s reach across Europe. Today, Doctrine serves 80 of France’s top 100 law firms and supports clients across the private and public sectors. The company is extending that leadership into Germany, Italy, Spain, and Luxembourg.
Guillaume Carrère, CEO of Doctrine, said, “By integrating Maite.ai, we are consolidating our position as the European leader in legal AI. As the global AI market rapidly takes shape, our ambitions remain focused on building a trusted European leader grounded in technological sovereignty. We are delighted to welcome Maite.ai to the Doctrine team. Last year was our strongest growth year to date, and this acquisition further accelerates our trajectory.”
Alejandro Castellano, CEO of Maite.ai, said, “Joining Doctrine gives us the scale and stability necessary to consolidate our leadership in Spain sustainably. By combining our technology with that of the European leader, we can offer our clients an even more robust solution, backed by ten years of industry expertise. This new chapter deeply respects our identity: Maite.ai will retain its brand, headquarters, and team.”
Maite.ai’s team will continue to lead the Spanish market, with significant hiring planned to support continued growth. The platform will benefit from synergies derived from Doctrine’s decade of expertise in artificial intelligence. This expansion positions Doctrine to serve the needs of more than one million lawyers and legal professionals across its markets, opening up major growth opportunities across Europe.
